VAT FOR DYEING, &G.

- SPECIFICATION forming part of Letters Patent No. 780,402, datedJanuary 17, 1905.

I Application filed September 9, 1904. Serial No. 223,890. l

To all whom, it may concern:

Be it known that I, JAMES Ai WILLARD, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented new and useful Improvements in Dyeing orBleaching Vats, of which the following is a specification.

This invention relates to vats particularly adapted for dyeing andbleaching, and aims 1 o to construct a vat for such purpose which shallbe simple in its construction, strong, durable, and efcient in itsuse,and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists inthe novel combination and arrangement'of parts hereinafter morespecifically described, illustrated in the accompanying drawings, andparticularly pointed out in the claims hereunto appended.

Ifn'describing the invention in detail reference is had to theaccompanying drawings, wherein like characters of reference denotecorresponding parts throughout 'the several Views, and in which- Fignrel is a sectional elevation of a vat constructed in accordance with thisinvention. Fig. 2 is a plan "view of the top or cover plate for the vat.Fig. 3 is a top plan view of the vat with the top plate removed. Fig. 4is av longitudinal' sectional view of the top plate when used forbleaching purposes,.and Fig.

5 is aL longitudinal sectional view of the bot` tom plate when used forbleaching purposes. A vat constructed in accordance with this 3,5Iinvention for bleaching or dyeing purposesl dium, and said receptaclemay be of any snitable contour and is provided in its bottom with anopening into which extends a dyeing or'bleaching medium supply pipe 2.The bottom of the receptacle 1 is also provided with an opening intowhich extends a steam-supply pipe 3, and upon the bottom of saidreceptacleA is arranged a perforated steam-pipe 4, whichv communicateswith the steam-supply pipe 3. The function of the steam-pipes 3 and 4 isto supply'steam to the bottom of the vat, so as to heat the bleaching ordyeing medium when occasion requires. The receptacle l in the sidethereof and at the top is formed with an outlet `5, said outlet 5 beingalways above the perforated top or cover plate to be hereinafterreferred to.

Arranged above the mouth of the supplypipe 2 and within the receptacle lis a deflector 6, which is adapted to deflect the medium supplied by thepipe 2, so that saidv medium will properly pass through the mass ofmaterial being treated, which would not be the case if the detlector wasdispensed with. Connected to orformed integral with the receptacle 1 insuitable relation with respect to the outlet 5 is a casing 7, forming anoverflowchamber 8 and in which isarranged a filtering medium 9 in closeproximity to'the outlet 5, said ltering medium 9 preferably being aplurality of wire screens. The function of the filtering medium 9 is toarrest the outiiow of any foreign bodies from the receptacle l, suchbodies tending to clog the suction-pipe 10, which communicates with thechamber 8.- A The supplemental bottom, carrying the material to betreated, is supported within the receptacle l and consists of a platecorresponding in contour to said receptaclel and which is indicated bythe'reference character 11 and suitably perforated throughout.Projecting from the bottomv of the plate l are a pair of annularsupporting members 12, which are angular in cross-section, and saidmembers l2 support the plate l1 a suitable distance above the bottom ofthe receptacle, forming thereby an auxiliary chamber for the receptionof the dyeing or bleaching medium. The plate 12 is further provided witha plurality of eyes or other equivalent devices 13 to permit ofattaching said supplemental bottom with a suitable hoisting device ofany description, so that said supplemental bottom can be re- *moved fromthe machine after the material Ahas been treated, carrying the materialtherewith, and which will also permit of the transporting of saidsupplemental bottom with the material to any suitable point desired.Through the medium of the eyes 13 and the hoisting device thesupplemental bottom can be replaced in position within the receptacle 1.The receptacle 1 is further provided with a removable top or closure andwhich consists of a plate 14, conforming in contour to the reeeptacle land which is perforated throughout. Upon the upper face of the plate 14,at the edge thereof, a reinforcing brace member is secured, whichextends entirely around the margin of said plate 14 and which is angularin cross-section. Secured to the upper face of the plate 14 is a seriesof segmentalshaped reinforcing members 16, which are also angular incross-section, and, further, secured to the upper face of the plate 14is a circular reinforcing member 17, which is also angular incross-section and which surrounds a spider 18,eonnected by suitableholdfast devices to the center of the plate 14. The central portion ofthe spider is reinforced by the plate 19, attached to the spider and theplate 14. The closure is further provided with a plurality of eyes orother equivalent devices to permit of connecting therewith a hoistingdevice, so that said closure can be removed from within thereceptacle 1. The closure also acts as a compression-plate for thematerial. Said closure is somewhat heavy and when placed upon thematerial and held down in a manner as hereinafter referred to thematerial carried by the supplemental bottom is compressed tosubstantially a solid mass. The means for retaining the closure inposition consists of a plurality of lockingdogs 20, which are adapted toengage the reinforcing member 15 of the closure, and said dogs are soconstructed and mounted that they can be swung into and out of thereceptacle 1. The dogs 2O are each provided with a hollow sleeve 21 topermit of the mounting of said dogs 2O upon a plurality ofvertically-extending slotted rods 22, which are secured at their lowerends to the heavy apertured lugs 23, connected with or formed integralwith the outer face of the receptacle 1. The rods 22 are secured to saidlugs 23 through the medium of the nuts 24. The locking-dogs 20 areretained in their locking position through the medium of the wedges 25,which extend through the slots of the rods 22, and when said wedges 25are driven home they securely retain the locking-dogs in their engagingposition with the closure.

When the vat is used for bleaching purposes, the lower face of theclosure and the upper face of the supplemental bottom are covered,coated, or sheathed with copper, lead, or other suitable metals notaffected by alkali or chemicals, as indicated by the reference character26.

From the foregoing construction of vat adapted for bleaching and dyeingpurposes a vat is set up which is unusually strong and durable, and aclosure for the vat is set up which is so constructed as to resist theimmense pressure necessary when circulating a liquid through thesolidmass of material being treated. The constructing of the closure inthe manner set forth prevents the bulging at the center thereof duringthe circulation of the liquid and the engaging of the lockingdogs withthe margin of the closure, also prevents the closure from bulging at itsedges. The closure when in position is always below the outlet of thereceptacle, so that during the bleaching or dyeing operation thematerial remains submerged at all times, which is due to the fact thatthe quantity of liquid supplied to the vat is such that the level of themedium will never fall below the closure.

It is thought the many advantages of a vat for dyeing or bleachingpurposes constructed in accordance with the foregoing description, takenin connection with the accompanying drawings, can be thoroughlyunderstood, and it will furthermore be evident that changes, variations,and modifications can be resorted to without departing from the spiritof the invention or sacrificing any of its advantages, and I thereforedo not wish to restrict myself to the details of construction ashereinbefore shown and described, but reserve the right to make suchchanges, variations, and modilications as come properly within the scopeof the protection prayed.
